When I try to compile the EA got two 2 errors.  “INIT FAILED“ - expression not boolean.

Both errors are the same.

'INIT_FAILED' - expression not boolean Auto ADX.mq5 line  279 column 20

'INIT_FAILED' - expression not boolean Auto ADX.mq5 line 285 column 17.

Where is the mistake in the code? Thank you for helping.

Ersetzen Sie die alte Funktion durch diese:

//| Lots or risk in percent for a deal from a free margin            |
//+------------------------------------------------------------------+

   if(lots<0.0 && risk<0.0)
     {
      Print(__FUNCTION__,", ERROR: Parameter (\"lots\" or \"risk\") can't be less than zero");
      return(false);
     }
   if(lots==0.0 && risk==0.0)
     {
